for large seeds I use Earthway Precision Garden Seeder. Saves on time and is wounderfull I have been using one for years. For small seeds I use a stiff poster board cut to about 4 inch square, The envlopes don't do well because of the glue on them, but you can use them if you put dirt on the sticky part. My daddy uses a bottle with a hole punched into the lid. The Earthway will plant most things that are okra size up to beans and corn and punkin
